Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] Such as figure 1 As shown, by setting the color filter layer 12 on the side of the light-emitting layer 11 close to the display surface, the reflection of external ambient light can be reduced, and the color filter layer 12 can also improve the light emitted from the light-emitting layer 11 through its filtering effect. color purity, but due to the different exit angles of the light emitted from the light-emitting layer 11, the actual distances passed b...

Abstract

An embodiment of the invention relates to the technical field of display, provides a display device and a preparation method thereof and realizes thickness reduction of the display device on the basisof reduction of external environmental light reflection. The display device comprises a substrate and a light emitting layer on the substrate and further comprises a color filter layer, the light emitting layer comprises a plurality of subpixels, and the color filter layer is arranged on one side, close to a display surface, of the light emitting layer and comprises a plurality of color resistance units. An orthographic projection, on the light emitting layer, of each of the color resistance units covers one of the subpixels. Each of the color resistance units is gradually thickened in a direction perpendicular to a plane of the substrate from the edge to the center of the corresponding color resistance unit.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a preparation method thereof. Background technique [0002] Compared with liquid crystal display devices, Organic Light-Emitting Device (OLED) displays have many advantages such as self-illumination, fast response, high brightness, high contrast, and thinness, and have gradually eroded the market of liquid crystal display devices. Its bendable and flexible characteristics have become the first choice for flexible display devices. [0003] However, since a large number of metal layers included in the OLED display have high reflectivity to external ambient light, the reflected light will affect the display effect of the OLED display device. [0004] In the prior art, a circular polarizer is placed on the light-emitting surface of the OLED display to reduce reflected natural light, but the thickness of the circular polarizer is relatively large, genera...
